Motorcycling Gearing Calculator

This is a great little number which allows you to enter a variety of
different values - gearbox ratios, tyre sizes, sprocket sizes etc -
in order to calculate the machine's speed in any gear at any given rpm.
Use is simplicity itself - just plug in the figures for your bike into
the pink column on the left side of the sheet. It's set up with standard
figures for a Ducati 916, and is in Zipped MS Excel 95 format.
